"When we walked out we could hear the bickering and fighting," said Diaz.

Officers were called to a home on the 1600 block of Alhambra, near West Avenue and Basse Road, around 7 p.m. Saturday. When officers arrived, they found the victim dead in the backyard. Officers believe the stabbing happened after a fight escalated quickly.

The victim is believed to be a Hispanic male in his forties. His name hasn't been released.

"To see somebody else in a body bag, I don't even know the guy," said Abigail Diaz. "I feel bad, you know what I mean. Nobody deserves that."

Nearby residents say they're surprised this happened in their neighborhood.

"It is scary, because he can come back and do it again, for all we know," said Noemi Diaz.

Police said they were receiving conflicting reports of the relationship between the suspect and the victim. Officers said the victim may have been living in the backyard shed.
